Abstract
The present paper contains a report on the first neutron radiography experiment that visualized the motion of solid particles in liquid gallium in a rectangular vessel, which was stirred by a system of four counter-rotating magnets. The experiment has demonstrated that the neutron radiography is a promising experimental method for the investigation of dynamics of particles in liquid metal. Tables 1, Figs 7, Refs 19.
